Hi @dnyc1000 We regret to hear you are having issues with your VAVA 4K UST Projector. Would you be so kind to try the following steps to see if it solves the issue?
Make sure it is not overheating and there’s enough space for proper air ventilation. It needs at least 30cm of space from the sides, for proper airflow. Try a power cycle of the unit press the power button for 5-10 sec, unplug from the wall outlet, restart the unit, check fan noise, factory reset and check what is the firmware version installed.
If the issue is still not fixed, kindly take a video of it and send it to email@example.com. Thank you!
